SHO, Here are some excerpts from a safety recall letter on this problem for 1996 & 1997 Explorers. Hope this helps. Dave.
******************************************
Ford Motor Company has decided that a defect which relates to motor vehicle safety exists in certain 1996 model year Explorer and certain 1997 model year Mountaineer vehicles.
Safety Defect
The lower right hand liftgate cylinder attachment bracket may separate from the bodyside. This may occur when the liftgate is being opened or closed or when the liftgate is in an open position. Unexpected closing of the liftgate caused by a separated bracket could result in injury to someone in its path.
Warning The vehicle should not be driven with its rear liftgate either fully or partially open. Harmful exhaust fumes could enter the passenger compartment if the liftgate were open. Also, cargo could fall out. Passengers may be at greater risk of injury, particularly in the event of an accident. Finally, damage to the liftgate cylinders and attaching hardware may result.
Repairs
At no charge to you, your dealer will reinforce the bracket with rivets. Dealers currently have instructions and parts ordering information.
Call Your Dealer
Call your dealer without delay. Ask for a service date and whether parts are in stock for Safety Recall 97S78.
If your dealer does not have the parts in stock, they can be ordered before scheduling your service date. Parts would be expected to arrive within a week.
